Abstract

<P>PROBLEM TO BE SOLVED: To inexpensively provide a spectacle frame which easily fits with anybody and is prevented from falling. <P>SOLUTION: Support pieces 3 are fitted to rear ends of both temples 2 respectively and both the support pieces 3 curve inward and are in a two-pronged shape comprising an outside piece 4 and an inside piece 5. Both the inside pieces 5 are flexible, and magnets 6 and magnets 7 which repulse each other are embedded at positions where the outside pieces 4 and inside pieces 5 are opposite to each other. When the spectacle frame is not put on, both the inside pieces 5 leave the outside pieces 4 with repulsive forces of the magnets 6 and 7 to deform inward. When the spectacle frame is put on, both the inside pieces 5 are pressed by the back of the head to approach both the inside pieces 4 as shown in Fig. 1. At this time, both the inside pieces 5 are pressed against the back of the head with the repulsive forces of both the magnets 6 and 7, so that the spectacle frame is securely held. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to a spectacle frame in which a face and a back of the head are sandwiched and held.

  For example, the following has been proposed as a spectacle frame that sandwiches and holds the face and the back of the head (see Patent Document 1). That is, in the spectacle frame including the spectacle frame temple having the first member, the second member, and the connecting member that connects the first member and the second member, the connecting member has flexibility and is external. The eyeglass frame is configured to switch between a first posture curved in a convex shape toward the direction and a second posture curved in a convex shape toward the inside. Put the front frame on the face in the second posture with the connecting member curved inwardly, and extend both temples from above both ears to the back of the head, and then turn the connecting member outward. When the first posture is curved in a convex shape, both the second members of the temple press the occipital region. The face and the back of the head are sandwiched, and the wearing of the spectacle frame ends. When removing the spectacle frame, it is only necessary to remove the spectacle frame by taking the second posture in which both connecting members are curved inwardly.

  The prior art has the following drawbacks. When both the connecting members are mounted by switching from the second posture bent in a convex shape toward the inside to the first posture bent in a convex shape toward the outside, the fitting member is always in a state of being firmly fitted to anyone. Not necessarily. That is, while the spectacle frame in the worn state is in a fixed state, the size and shape of the head are greatly different for each person. Therefore, there is no choice but to prepare a product that fits each person, that is, to produce a special product for each person. This is cumbersome, time consuming and expensive.

  The problem to be solved by the present invention is to provide an eyeglass frame that fits easily to anyone and prevents slippage at low cost.

  The spectacle frame according to claim 1 has a front end of a rod-shaped temple 2 extending rearward to the left and right of the front frame 1, and a front end of a bar-shaped support piece 3 extending rearward to the rear end of the temple 2. Each of the support pieces 3 has a bifurcated portion made up of an outer piece 4 and an inner piece 5 as a shape that curves inwardly, and both the inner pieces 5 are assumed to be flexible. In addition, magnets 6 and 7 that repel each other are provided at opposite positions of the inner piece 5.

  When this spectacle frame is not attached, the inner pieces 5 are separated from the outer pieces 4 and deformed inward by the repulsive force of the magnets 6 and 7. When worn in this state, the inner pieces 5 are pushed by the back of the wearer and approach the outer pieces 4. At this time, the repulsive force of both the magnets 6 and 7 becomes an urging force, and both inner pieces 5 are pressed against the back of the head, so that the spectacle frame is firmly held. When the spectacle frame is removed, the inner pieces 5 are separated from the outer pieces 4 by the repulsive force of the magnets 6 and 7, and return to the original positions inside.

  According to a second aspect of the present invention, the spectacle frame according to the first aspect is characterized in that the support piece 3 can be adjusted back and forth with respect to the temple 2. For example, the following is conceivable as a method for adjusting the support piece 3 in the longitudinal direction. In other words, a hole in which the rear part of the temple 2 fits a little tightly is formed from the front end of the support piece 3 and the rear part of the temple 2 is passed through the hole. And the support piece 3 is moved back and forth with respect to the temple 2, and it adjusts to the position which fits a wearer exactly.

  In the spectacle frame according to the present invention, the magnets 6 and 7 that repel each other are provided at positions opposite to the outer piece 4 and the inner piece 5, and the inner piece 5 is urged forward with respect to the outer piece 4. And the dispersion | variation in the magnitude | size and shape of a wearer's head can be absorbed within the range which can deform | transform while the inner piece 5 receives biasing force. Therefore, the range of wearers to which one product can be applied is considerably widened. For this reason, it is not necessary to produce so many types, leading to the point that it can be provided at low cost. Further, as described above, when the spectacle frame is mounted, a forward biasing force is applied to the back of the head by magnetic force. For this reason, it fits many people and prevents the glasses frame from slipping down. In the case of the spectacle frame according to the second aspect, the support piece 3 can be moved back and forth with respect to the temple 2 and adjusted so as to fit the wearer.

  The best mode for carrying out the present invention will be described with reference to FIG. FIG. 1 is a plan view showing a state in which a spectacle frame is mounted. Reference numeral 1 denotes a front frame. Front ends of rod-shaped temples 2 extending rearward are attached to the left and right sides of the front frame 1, respectively. A front end of a rod-like support piece 3 extending backward is attached to the rear end of the temple 2. That is, a hole into which the temple 2 enters a little tightly is formed from the front end of the support piece 3, and the support piece 3 is connected to the rear end of the temple 2 by passing the temple 2 through the hole. And both the support pieces 3 are each made into the shape which curves inwardly like a bow. The rear half of the support piece 3 is formed in a bifurcated shape and is composed of an outer piece 4 and an inner piece 5, and the rear end is integrated. Both the inner pieces 5 are flexible, and the vicinity of the rear ends of the inner pieces 5 is formed in a shape that bulges slightly forward. In the bulging position, the magnet 6 and the magnet 7 are embedded in the outer piece 4 and the inner piece 5 so as to face each other. The magnet 6 and the magnet 7 are opposed to each other with the same polarity.

  When this spectacle frame is not attached, the inner pieces 5 are separated from the outer pieces 4 and deformed inward by the repulsive force of the magnets 6 and 7. When worn in this state, as shown in FIG. 1, both inner pieces 5 are pushed by the wearer's back head and approach both outer pieces 4. At this time, both inner pieces 5 are pressed against the back of the head by the repulsive force of both magnets 6 and 7, and the spectacle frame is firmly held by the urging force of both magnets 6 and 7. When the spectacle frame is removed, the inner pieces 5 are separated from the outer pieces 4 by the repulsive force of the magnets 6 and 7, and return to the original positions inside. In addition, it can be made to fit a wearer exactly by adjusting the length which pushes the temple 2 into the support piece 3. FIG.

It is a top view which shows the best form for inventing.
